Introduction
Introduction
1.2.1: Location and storage
1.0: Scope
Introduction is a general description of system
characteristics of the product, its intended use and
applicable electrical, mechanical, and environmental
specifications, voltage requirements, AC input,
and circuit breaker readings.
1.1: Section descriptions
This manual is divided into three sections:
Section 1: Introduction
This section is a general description of the Power-Suppress
100 ultra-isolator. The section includes receiving, electrical
and mechanical specifications, and cabinet measurements.
Section 2: Installation
This section guides the user through installation
requirements, wiring and circuit diagrams, hardwired
connections, and factory configuration ratings for the
Power-Suppress 100.
Section 3: Maintenance and troubleshooting
This section contains preventive maintenance for the
Power-Suppress 100 unit and a troubleshooting guide
to assist the user with any communication or configuration
connections.
1.2: Receiving
The unit is convection-cooled, with the air vents located on
the sides and top of the unit enclosure. Therefore, it should
be installed in a clean, dry place with enough clearance
to allow a free flow of air. Allow at least four inches of space
between the unit and the wall or other equipment for portable units. Allow enough space for maintenance on all four
sides on larger units. Never mount one unit over the other;
heat rising from the unit may cause premature failure.
Never install the unit near a heat source.
Note:
If the unit is to be mounted vertically, the surface
area must be capable of supporting at least four
times the unit’s weight. (See Table 1-2—page 3)
Locate the conduit knockouts at the bottom, with
the mounting slots in the mounting brackets facing
down. Transfer the hole pattern from the unit
to the mounting surface and drill the holes,
refer to dimensions for hardwired enclosure
(See Figures 1-2 and 1-3—page 4 and Figure
1-6—page 6). Use at least 0.25-inch hardwire
(minimum grade 5) to attach the unit to the
surface, with 6.00-inch clearance around
the unit for air flow.
If the equipment is to be stored prior to installation,
it should be stored in a cool, dry, well-ventilated
location that is protected from rain, splashing water,
chemical agents, etc. The equipment should be covered
with a tarpaulin or plastic wrapper to protect it against dust,
dirt, paint, or other foreign materials.
Figure 1-1: Vertical mounting drawing
Before accepting the shipment from the freight carrier,
inspect the exterior surfaces of all shipping containers
or packaging used, and the equipment for damage that
may have occurred during transit. If the shipping containers
or equipment shows evidence of damage, note the damage
on the receiving document (bill of lading) prior to signing
for receipt of equipment.
All claims for shipping damage must be filed directly
with the carrier. Replacements for damaged components
should be ordered through Eaton.
Check by thorough inspection if any electrical connections
have become loose because of vibration during shipment.
Check the nameplate to be sure that the voltage and
frequency match the available power supply. Under no
circumstance should the unit be connected to a power
source that does not conform to the nameplate rating.

Power-Suppress 100 installation and user manual IM01002003E August 2013 Eaton.com
Introduction
1.3: Prerequisites to installation
●●
An efficient installation depends on careful planning and site
preparation. Installation of the equipment must be handled
by skilled technicians and electricians familiar with the
special requirements of high-voltage electrical equipment.
The installation must comply with the requirements
of the National Electrical Code (ANSI/NFPA 70, latest issue)
and local codes as applicable.
1.4: General description
The overall function of the Power-Suppress 100 is to
attenuate transients and noise that originate on incoming
power lines and to provide a newly derived, isolated
power source.
The Power-Suppress 100 is used to protect sensitive
electronic equipment and computers from power-line noise
and transients. There are common disturbances on power
lines caused by lightning, motor starting and stopping,
utility network switching, and general electrical noise,
which will adversely affect sensitive electronic equipment,
especially computers.
The Power-Suppress 100 utilizes a unique method
of shielding and isolation that provides low capacitive
coupling between input and output circuits. This low
capacitance, together with a highly effective filter circuit,
results in ultra-high common mode and normal mode
noise attenuation.

at the Power-Suppress 100 unit.
2. Verify that the input source voltage is compatible
with the input jumper configuration. If not, change
input jumper configuration accordingly.
Note: Changing from an input of 120 Vac to an input
of 240 Vac on hardwired models rated at
1000 VA and below requires that the input fuse
be changed as indicated. A fuse rated at 240 Vac
and the correct amperage has been provided
with the Power-Suppress 100 and is located
inside the enclosure, labeled “240 Vac fuse”.
In order to access this fuse and configure the
Power-Suppress 100 input for 240 Vac, the unit‘s
cover must be removed. This is accomplished
by removing the six screws that hold the cover
in place. These screws will be required when
re-securing the cover, once the Power-Suppress
100 is properly configured.
See Figures 2-1 and 2-2—page 8, Figure 2-3—page 9
and Figure 2-4—page 10, for typical wiring diagrams
of electrical hookup.
3. Verify that the output voltage required by the load
is compatible with the output jumper configuration.
If not, change output jumper configuration accordingly.
2.2: Installation of hardwired models
4. Once configured properly, make sure power
is “off”, then connect the input source voltage wires
to the terminals provided. Verify connections are tight
and energize the unit (see Table 2-1—page 7).
The Power-Suppress 100 ultra-isolator is shipped from
the factory configured for an input and output of 120 Vac,
except for 5 kVA and 7.5 kVA models provided with
an input of 240/480 Vac, which will be configured
for an input of 480 Vac and an output of 120 Vac.
5. Verify that the output voltage is within
nominal specifications.
6. Turn the power “off”. Connect the output (load) wires
to the terminals provided. Verify connections are tight,
replace the unit‘s cover and re-energize the unit
(see Table 2-1—page 7).
7. 1800–7500 VA models configured for an input
of 240 Vac or 480 Vac require a 2-pole input circuit
breaker, as specified in Figure 2-4—page 10, provided
by the customer.
8. All models rated 1000 VA or greater require an input
circuit breaker as specified in Figure 2-4—page 10,
provided by the customer.

Maintenance
3.2: Troubleshooting
3.0: Scope
Corrective maintenance might have to be performed on any
of the three main components in the Power-Suppress 100
ultra-isolator: transformer, filter card, or input fuses.
This section contains preventive maintenance for the PowerSuppress 100 units and troubleshooting to assist the user
with any communication or configuration connections.
WARNING
High voltage: All power must be “off” prior to any
maintenance. Only qualified electricians should perform
maintenance or troubleshooting.
3.1: Preventive maintenance
To ensure longer component life and trouble-free operation, minor preventive maintenance procedures should be
performed at regular intervals, for example, once every year.
More frequent inspection intervals would be needed for
more severe operation conditions.
1. Transformers: The transformer is designed with
a considerable safety margin. Normally, the only
malfunction that can take place is a short to the core.
It can be checked easily with an ohmmeter.
2. Filter card: MOVs can fail open or capacitors
can be defective in the open or shorted mode.
These can be checked easily with an ohmmeter.
Visual inspection may also allow detection of failed
components.
3. Input fuse: The unit‘s input fuse can clear (open)
due to a fault or overload condition at the output
of the unit or in the rare case of a transformer failure.
A fuse is easily replaced via the flush-mounted fuse
holder located on the back of the enclosure. Before
replacing a fuse, the load should be removed or disconnected from the unit and a visual inspection inside the
unit should take place.
At each service inspection, remove any dust, dirt, or foreign
particles. A slight tug should be used to test if there are any
loose electrical connections.
